IL-2 signaling and CD4+ CD25+ Foxp3+ regulatory T cells.

چکیده
Although originally described as a potent T cell growth factor in vitro, the main non redundant role of interleukin-2 (IL-2) in vivo is now known to be the maintenance of peripheral T cell tolerance. As well as promoting the proliferation and survival of recently activated effector T cells, IL-2 also plays a critical role in regulatory T cell (Treg) homeostasis and has been variously described as promoting the thymic development, peripheral homeostasis and suppressive function of Tregs. These observations, stemming largely from studies on various murine models of IL-2 and IL-2 receptor deficiency, have prompted a greater understanding of the pro-tolerogenic nature of IL-2 dependent signaling. Here we discuss current knowledge concerning the importance of IL-2 mediated signaling in Treg biology as well as its relevance to possible therapeutic applications.

Induction of T Regulatory Subsets from Naïve CD4+ T Cells after Exposure to Breast Cancer Adipose Derived Stem Cells
Background: Adipose derived stem cells (ASCs) provoke the accumulation and expansion of regulatory T cells, leading to the modulation of immune responses in tumor microenvironment. Objective: To assess the effect of tumoral ASCs on the trend of regulatory T cells differentiation. Methods: Peripheral blood naïve CD4+ T cells were co-cultured with ASCs derived from breast cancer or normal breast ...
متن کاملNumerical status of CD4+CD25+FoxP3+ and CD8+CD28- regulatory T cells in multiple sclerosis
Objective(s): Regulatory T cells, including CD4+CD25+Fox3+ and CD8+CD28- cells play an important role in regulating the balance between immunity and tolerance. Since multiple sclerosis is an inflammatory autoimmune disease, regulatory T cells are considered to be involved in its pathogenesis. In this study, we investigated the circulatory numbers of the two mentioned types of regulatory T cells...

Background: Brucellosis is one of the most common chronic diseases, with widespread distribution. In spite of cell-mediated immunity (CMI) modulated mainly via activated T-helper type 1 (Th1) cells, brucellosis can advance to chronic disease in about 10-30% of cases. Regulatory T cells (Treg cells) are involved the immune response to brucellosis; however, their role, particularly in...
